Cascadia is gonna snap!

Thanks! I'm in Puget Sound and always watching and listening.

My gut feeling is that the big one will hit Washington coast on Sunday the 27th of this month. I have gone so far as to call a family member that lives in Seattle and invited him to come here to eastern WA. for the week-end.

What causes you to believe the loading is on the Seattle area fault?

My observations show a normal spring grind.

Speaking of patterns, have you noticed that once a week, since the 7 in Chile a month ago, there has been a large quake in the high 6's to mid 7's, moving continually north. It started in Chile, then about a week later, the one in Nicaragua, then another week, the one in Mexico. One week from Mexico, and we have Vancouver Island. If the pattern continues, around the 1st of May will bring a big Surprise. If it does continue, will it go north, south, or just squat down on the Cascadia Subduction zone?

I have said for many years, my gut tells me the big one will be the Juan de Fuca or Cascadia. Time will tell.

I actually just recently downloaded The Global Earthquake Explorer (seems to be the best software for linux) and been exploring its limited features, I was noticing that northward trend when messing with the slider to show period of EQs over the longer periods of time. Time will tell I guess. I keep two BC seismos up all the time now.. Living right on the water in the Puget sound so hoping for the best.

Hopefully the pattern ends with this last quake, but it's always helpful to be prepared and know your surroundings, and what it is capable of.

I also don't think that it's a well known fact there is a Caldera at the base of the Juan de Fuca in Oregon, that was shown in a video of scientist's taking recordings of cable laying on the ocean floor last year. They mentioned (and showed), that there was evidence of very recent activity, framed by evidence of activity thousands of years old. Which to me means what is happening down there now, hasn't happened in thousands of years.

I am sort of new to the PNW area - is the "big one" that is possible, when affecting seattle and surrounding areas, would the actual quake be, say near the 6.6 in Canada? Or can the 9.0s happen inland?

Hi. I'm EAT. I agree... the big one is mere moments away.
Moments. Within the next 6 days.
Take care my friend,
-EAT

I'm thinking that the release point will be in Alaska

OP and all -

I did some research back in October and found a ton of info on the area...I posted a thread about it.

Thread: Cascadia Subduction Zone research (and links)....Could this be the area where the "big one" occurs?

Didn't get much attention then, but it is solid research with links, and it now may be more interesting with all the activity

There was a show on the history channel called megaquakes. One scientist was doing work on a bank of a river somewhere in Washington state near the subduction zone, and he said he saw proof of what would have been equal to a 10, that happenend before recorded history. So the answer is yes, the area can produce up to a ten.

It also said if the Juan de Fuca slips, it would be similar to the quake in Indonesia, except the Tsunami could be over 200ft high, with a 15 minute warning.

In the past, when the Cascadia has had a major quake, it caused "orphan tsunamis" in Japan. They called them "orphans" because the never felt the EQ that caused it...

...it was on the other side of the ocean!

We are in the time frame for another big one.

This is from my thread, but I saw some of yall's posts and wanted to share this article

"It turns out that Cascadia is virtually identical to the offshore faults that devastated Sumatra in 2004 and Japan in 2011—almost the same length, the same width, and with the same tectonic forces at work. Cascadia’s fault can and will generate the same kind of earthquake we saw last year: magnitude 9 or higher. It will send a train of deadly tsunami waves across the Pacific and crippling shock waves across a far wider geographic area than all the California quakes you’ve ever heard about."

For every action, there is an opposite and equal reaction. One of the prime rules of physics, and certainly applies to EQ's.

Yeah, a 9 ish quake on cascadia could cause a big enough tsunami in japan to take out fukushima again.....
damn, thats scarier than the idea of the megaquake......

NEXT X CLASS FLARE WILL RELEASE CASCADIA ......

I have read that the 9.2 in Alaska in 1964, released a tsunami 67 meters high at its peak.

In 1958, also in Alaska, the biggest tsunami ever recorded, at 1720 feet, was caused by a rockslide.

Juan de fuca plate is like a knife and when it is under strike slip pressure for a sustained period of time it has shown a tendancy to dive at the knife edge on the eastern side. This promotes the likelyhood of a Cascadia subduction. Still this only increases probability and is in no way set in stone.

This event would not likely be inland but rather 100 to 300 miles off shore. This would still be a bad senario. Even if it was a mere 6.8 as subduction is the worst case senario capable of creating devastating tsunamis just like the one in japan.

I beleive that it would occur on the Cascadia but very near the Jaun de fuca.

^this guy dont know what the F hes talking about...

It can make EQs up to 9.8, after the japan quake they analyised that earthquake and maped the casscadia subduction zone and realized that with how the ground over lays each other on cascadia that the Mega trust would be inland 100 miles... In other words the 6.5 and 7.5 leading up to the big one will be offshore but the mega thrust will be deeper and happen inland.. New studys sugest

"In this mirror image, one can see that if the same earthquake occurred in Cascadia, the fault would rupture to a significant distance inland, since the Cascadia trench sits much closer to the coastline than the trench off the coast of Japan," Anderson said. from link less then 50% [link to usnews.nbcnews.com]
